Optics Introduction to Diffraction Grating
Transmission and reflection gratings have comparable efficiencies, which can be optimized for a specific spectral region by selecting the appropriate groove spacing and blaze angle. Transmission gratings are relatively insensitive to the polarization of the incident light. Thorlabs offers gratings optimized for UV, near IR, and visible ...

The modeled laser pulses (top) and CW laser output (bottom) provide the same energy per period, illustrated by the shaded areas. The CW laser's output power equals the pulsed laser's average power.
